Hie, have a smart 323 which l love but lately when l try and start the car it wont start until l press the accelerator. When it doesnt start and l turn the key there has been an incidence where smoke has come from there and l got so freaked out l called the breakdown and they said have an ignition problem, it also shakes when am idle whilst driving it. Please help as l love this car and so far have not had any problems until now, Thanks!
